Last time, is a C-notch really necessary? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, I think we decided a while back that on a stock height truck the distance between the top of the wheel arch to the center of the wheel is approx. 22" (on the rear). So to find the amount of suspension drop, simply find the measurement between those two points and subtract that number from 22". Obviously the same can be done for the front end, but I think we decided on about 19" for the front stock height. Tire size has nothing to do with the amount of suspension drop but will affect overall drop of the truck. In my opinion if I were doing a 6" drop in the rear, I'd install a c-notch and get the adjustable panhard bar.

@pbmcauliffe

I dont have an answer to your question, but your truck looks sharp. What wheels are those? smooooothies?

Those are smooothies, and that "is" a sweet 67, but your pic needed some help-

If you look real close, I think those are chrome vette style rally wheels.

I agree!

Yep, chrome Corvette ralley style, 15x10 in rear, 15x8 in front. I am not a big ralley wheel fan, so they are going to be sold after the holidays when I redo the suspension and go to 18's.

So I just measured my truck against what Slammed67 said. I came up with 16" from the top of the wheel arch to the center of the wheel. That equals 6" drop. I always thought I had about 5". I have about 2" clearance at the frame rail. I have no bump stops back there and have NEVER hit the frame. This is my daily driver and I drive a lot. I would say I don't need a C-notch at all. So install the springs first and see how it is before you hack up your frame. Good luck.

Well, doing the measurement method, I am coming up with approx. 8" of drop (22-14=8) so I guess I need to c-notch it to get more than my current 1" of clearance between frame and axle.
